Application filed March 23, 1918. Serial No. 224,319.

To all whom it may concern: I

Belt known that I, LOUIS BRUDICK, a subject of the Emperor of Austria, residing at Raiston, county of Lycoming, and State of Pennsylvania, have invented certain new and useful Improvements in Envelop-Openers, of which the following is a specification.

This invention relates to improvements.

in envelops and. has as its special object the provision of means whereby an envelop may be opened in a rapid and convenient manner by means carried within itself.

A further object is to provide an envelop which may be'used for letters or. like inclosures and which is unobjectionahle in appearance or use from any view point whatever.

The invention includes the novel arrangement of parts hereinafter described and shown in the accompanying drawing, forming a material part of this disclosure, and in which Figure 1 is a fragmentary perspective view of an envelop, parts being broken away in order to show the'openingdevice as applied thereto.

Fig. 2 is a fragmentary side elevational View of an envelop as it appears before Fig. 3 is another side elevational view of'an envelop indicating the method used in opening the mole.

F' 4 is a like side elevational view showt e envelop partially open. a

ig. 5 is a wctional view, loofing on line 5-5 of Fig. 2, and

Fig. 6 is a fragmentary side elevetional view of the opening device in w The invention may be applied to any ordinary form of commercial envelop, as dimted icy the numerallO, provided with the usual closing lap 11 and ads. ted to concharacter whatever.

e-|- -11 to one of the lower corners of the envelop eon the front 12; and back thereof is a oli id, in which-1s d end ofane he: cord .15, to the outer free end of which is fastened a hook-like element 18, the inner edge of which is reduced in thickness and fashion in the form of knife blade or cutter so arranged as to normally rest over the folded edge at the end of the envelop, as indicated in Figs. 1 and 2. i v

In operation, the envelop having been filled with whatever-inclosures desired and properly sealed it is in condition to be mailed: When received and at the time it is desired to open the envelop, the extending hook element 18, is grasped by thefingers, as clearly indicated in Fig. 3, and raised upward so as to tension the-elastic fibers of the cord 15, whereupon, it being suddenly released. the interior sharpened edge; of the element comes in violent contact with the folded edge, severing the same and, do to the elasticity of the cord material, forcing the hook 18 nearly or quite to the end posite lower corner, closely adjacent .to the; clip 14, thereby be opened without further dificulty: Having thus described my invention what I claim as new and desire to secure by Let ters Patent, 1 I

1. In an envelop opener, the combination with an envelop, of a clip secured at one permitting the" envop to;

of the lower corners thereof between the formed therewith engaged with said elastic cord at its opposite end.

I 2. In an envelop opener, the combination 1 with an envelo of ordinary commercial 1: of an elastic cord secured between the inner and outer walls of said envelop at one of the lower corners thereof, said cord extending through at the OPPOSltB upper corner, and a shaped cutter element secured to the end of said elastic cord, said cutter element extendinginto position toheoper 3. In an envelop opener, the hmation with a commercial envelop, of e clip onat one of the lower-ere thereof,

523 memes:

an elastic cord. secured in said clip, said operable whereby said elevetic 00rd, aiue to elastic cord extending closely adjacent to its elasticity, causes thefeielerfi eflge or seam the folc'ied edge of the envelop, a cutter of the envelop t0 besevezied, 10 formed in the shape of a hook secured to In testimony whereof I have efixed my a the free end 0f said elastic cord, said cutter signature.

being adapt/ed to engage with the folded I I edge opposite to said clip, said cutter being LOUIS BRUDICK.
